eczema smear @FFHQE HOWARD I. ARNOLD, OF RQCKLAND, SSACH'USETTS FLYER OR TRAVELER FER SERVING MACHDV'ES/ Application filed March 31, 1930. Serial No. 440,419.

This invention relates to flyers or travelers for serving machines, that is, machines which are constructed to wrap or serve a thread, cord or Wire around a core, and it has for its object to provide a novel traveler or flyer which can be made relatively light in weight so as to have relatively small inertia and thereby produce a relatively small drag or tension on the serving arn when the latter is of light weight, an which is also provlded with means for easily increasing the weight of the flyer or traveler when more drag is necessary, as is the case when the serving yarn is of a heavier character.-

Furthermore, my invention is so constructed' that when the machine isstopped the flyer or traveler will not overrun and cause a loose and consequently imperfect place in the cover. It is further provided with a novel guiding surface which serves to evenly distribute the serving yarn on the core.

In order to give an understanding of the invention I have illustrated in the drawings a selected embodiment thereof which will now 'be described after which the novel features will be pointed out in the appended claims.

In the drawings:

Fig. 1 is a sectional view illustrating a device for wrapping or serving a core;

Fig. 2 is a perspective view of the flyer or traveler.

The serving machine herein illustrated is similar to that which is shown and described in my co-pending application Serial No. "430,305, filed February 21, 1930.

This device comprises a hollow non-rotary spindle member 1 which is suitably supported in a bolster member 2 secured to the frame 3,

the spindle 1 being hollow to permit the core "4 which is to be covered or served to pass axially therethrough.

The yarn or cord which is to be served about the core is indicated at 5 and it is taken from a yarn carrier 6, herein shown in the form of a spool. This yarn carrier 6 is in turn carried by a rotating tubular member 7 which is rotatably mounted on the spindle member 1, said tube 7 being driven by a whirl 8. ,At the upper end of the yarn carrying member is a tubular guiding member 9 which fits over the'upper end of the tube 7 and which has a flange 10 that rests on and is interlocked with one of the heads of the spool. At the upper end of the guiding member 9 is a head 11 provided with a cylindrical portion, terminating in an annular edge 12 which is coaxial with but well spaced from the core and over which the yarn 5 passes and with which it has contact.

The traveler or flyer which embodies my so present invention is shown at 13. The body thereof is made of some light fibrous material such, for instance, as paper and it is formed wlth an aperture 14 throu h which the guiding tube 9 extends. This yer normally rests on the flange 10 and it has extended radially therefrom a wire stem 15 which terminates In an eye 16 through which the yarn or cord 5 passes. The wire stem may be secured to the body 13 in any appropriate way. As 7 herein shown the wire is formed into a loop 17 which extends through the body 13 adjacent one edge thereof, the wire from the loop being flattened down and being thereby clamped to the body. 0 The body portion 13 of the traveler or flyer 1s made narrower at the portion 18 where the mm is secured thereto and then at the opposite side 19, said body portion having a en= eral sector shape. This shapeprovides a alanced flyer since the extraweight of the material at the wider side of the body balances theweight of the wire 15.

The body 13 is relatively thin and being made of paper or paper stock it is extremely light in weight. The character of the material forming the body 'may be varied, how-.. ever, without departing from the invention so longas it is relatively light in weight.

The head 11 which acts as the guiding surface is preferably adjustable so that when the yarn 5 passes from the eye 16 to the serving point 21 it will engage the rounded edge 12 of the head 11. When the spindle is in motion 95 the upward movement of the yarn 5 through the eye 16 will tend to lift the flyer from the flange 10 and this action will reduce the friction of the flyer on this surface. Conversely, when stopping the machine the flyer will 1 00 drop back on flange and the increased friction will stop all tendency to overrun. J

Since the flyer is relatively light it will have very little inertia. This is an advan- 5 tage because when the machine is started up the yarn is not subjected to any unusual strain due to the inertia of the flyer. Furthermore, when the machine is stopped there is fio danger of the flyer overrunning due to its inertia. The overrunning of the flyer would cause a spot where the serving is loose.

It is sometimes desirable to increase the drag on the serving yarn 5 especially if the yarn is of a heavier character. One way of accomplishing this is by adding weight to the flyer 13 and this may be done by superposing onthe flyer one or more washers of metal or other material. The tension or drag on the yarn 5 may also be increased by using a flyer with a heavier stem 15. The placing of added weight in the stem 15 serves to throw theflyer slightly out of balance which will produce a frictional engagement between the flyer and the tube 9 and will thus increase the drag on the yarn.

' I claim:

1. In a serving machine, the combination with a rotatable yarn carrier arranged coaxially with the core to be served and having a flyer-supporting flange and an upstanding tubular portion risingzfrom said flange and through which the core extends, of a head at the upper end of the tubular portion provided with an annular thread-guiding edge situated coaxially of the yarn carrier and well spaced from the core, a flyer adapted to rest on said flange when the -machine is at adjustably carried by the tubular portion at its upper end and provided with a cylindrical portion presenting at its end an annular thread-guiding edge coaxial with but well spaced from the axis of the head, a flyer adapted to rest on said flange when the machine is at rest, said flyer having a radiallyrest, said flyer comprising a sector-shaped body portion of paper material through which the said tubular portion extends and a wire arm extending radially from the narrow I end of the body portion and terminating in a guide eye for the serving yarn, said guide eye and guiding edge of the head having such relation that the serving yarn contacts with said edge in passing from the guide eye to the core to be served and the movement of the serving yarn through said guide eye whe the machine is inzmotion tending to raise the flyer from the flange.

2. A flyer for a serving machine comprising a thin flatsector-shaped body por tion of light fibrous materi and a wire stem extending from the narro end of the body portion and terminating i a guide eye, said body portion having an o ning to receive a guide member, the combined weight of the stem and the narrow end of the body portion counterbalancing the weight of the wide end of said body portion.

.3. In a serving machine, the combination with a rotatable yarn carrier having a flyer; supporting flange and an upstanding tubular portion rising from said flange and through which the core to be served passes, of a head.
